Antisense compounds, compositions and methods are provided for modulating the expression of PKA regulatory subunit RII alpha. The compositions comprise antisense compounds, particularly antisense olig
Inactivation of CHS by iodoacetamide and iodoacetic acid targets Cys164 in a pH-dependent manner (pKa = 5.50). The acidic pKa of Cys164 suggests that an ionic interaction with His303 stabilizes the thiolate anion. Consistent with this assertion, substitution of a glutamine for His303 maintains ...
1.00 M acetic acid, K_a=1.75 times 10^{-5}, and 1.00 M sodium acetate to make a buffer. What is the maximum buffer capacity of pH? A buffer solution is made using a weak acid, HA, with a pK_a of 4.63. If the ratio of A^- to HA is 1.0 \times 10^2, what is the pH ...
The pKa of HF is 3.17. Calculate the Ka of an acetic acid solution if the pH is 4.76 and concentration is 176 mM. Calculate the concentration of free Ca2+ in a solution of 0.10 CaY2- at pH 10.0. Use the followin...
Theoretical chemistry methods have been used to study the molecular properties of antiplatelet agents (ticlopidine, clopidogrel, prasugrel, elinogrel, ticagrelor and cangrelor) and several thiol-containing active metabolites. The geometries and energies of most stable conformers of these drugs have been co...
What formula do you use to determine if an acid is protonated or deprotonated when given the pH and {eq}pK_a {/eq}? Acid-Base Reactions: Acids and bases mainly react to form neutral solutions, a reaction termed neutralization reaction. protonation of any ...
HClO is classified as a type of acid and it is called as hypochlorous acid. This acid is considered as an oxyacid of the halogen chlorine. This acid is categorised as a weak acid.Answer and Explanation: Given: {eq}pK_a {/eq} of 7.54 Molarity= 0.110 M Calculations: ...
